of descending air produces stable atmospheric conditions over most of its surface area, and the climate generally is dry.
I also explained why the extra warmth at the surface is provided by compression

Whereas the CO2 has reduced the rate of uplift in the ascending column (which warms the surface) CO2 at lower levels reduces the rate of descent in the descending column which reduces surface temperature because less warmth is then being generated via compression
of descending air.

By the use
of a spring the tension is increased as the
air is exhausted and the spring is compressed and decreased as the spring resumes its normal shape, which by the use

Cold
air at the top
of ascending columns is forced to one side by warmer
air continuing to flow up from beneath but it is blocked by the warmer stratospheric
air above and so flows laterally and downward to the top
of descending columns, following the undulating slope
of the tropopause.
Recall that the
air flowing across laterally and downward to the top
of the

descend.
